A spring bb gun has a spring constant of 1000 N/m. If the spring is compressed 2 cm, with what speed does the 2 gram bb leave the bb gun with? (don't forget to convert grams to kg first) A. 9.5 m/s

B. 11.9 m/s

C. 14.1 m/s

D. 15.7 m/s

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

0.19 m/s and 0.45 m/s
